From what I've seen, teachers generally tell students to stay away from Casios, because of the difficulty in getting students to understand using them.
It would happen to be David...and I see you went to National Mathcounts too! I just back... stupid U.S. Airways. Probably will never see my coach for a LONG time, might see him when I volunteer to score at States next year though, so no chance of getting a CAS.
Guys, I've got a CX on me now, donated by TI. I like it, for math, that is. I don't program that much, and never did on my TI-84 SE. The higher resolution and color display is a godsend with graphing functions, . The menu setup will take a little getting used to. There is a menu button that is like the File on Windows, with everything under it, but commands may be accessed by typing, for example, SUM. The buttons are hard press, not soft like the 84. You can have different documents with 4 pages of different added functions, like lists and spreadsheet, graph, etc. It does more than the 84's, but I wish I had gotten the CAS version (I was given CX because it can be used on standardized tests). The 84 still is faster to use, but not drastically so. I'll be using the CX instead for most math.
